I’m getting so fed up. I’m using a TP-Link Deco M5 mesh system and although it does a great job for everything else, Sonos seams to really hate it. When I say hate it, it literally won’t find anything?

I’ve gone down the tech support option - got cut off of course🤬

Ive rebooted the router. I’ve rebooted the Deco’s and rebooted all the speakers and amp. 
 

Ive gone to put a bit of music on and obviously I can’t connect to any speakers. 
 

Im so fed up of this. Any help would be great fully appreciated.
